How do you tell a friend to stop his affairs

I would say it depends on a number of things. How much information about this did you get from his wife? Just a request or details? How close are you to this friend? How do you feel about what he is doing? How responsible to his wife do you now feel? I personally would have lost a bit of respect for him. Perhaps not enough to end the friendship but enough to risk it. You can go several ways with this. Ignore it. In casual conversation bring up that you heard he was having an affair and see where it goes. Tell him in no uncertain terms that you feel really bad about what he is doing to his wife. And a whole number of other things. It all depends upon how you feel about what he is doing and the responsibility you may feel to his wife. She did ask for your help. No easy way out of this but I think you know what the right way is.

Unless you are really close to the person you are suppose to approach I woud say "mind your own business" ..I wouldn't get involved.. Let the wife do it or have her call "cheaters" the tv show that really catches up on all that stuff.

I would stay out of it.If you don't want to risk a friendship ! You have to know that after this blows over for them ,you may have said something that they blame you for. This is just the way people are ,easier to focus on something else than to face a problem.

yeah i would stay out of it, unless they are really good friends. then all you can do is striaght up with them.

You could start by asking him if he likes being married. If he responds by saying that he does, then you could point out that he has a lot to lose if he carries on in the way he does. If he says he doesn't like being married, then not much can be done.

It is not an easy task for a friend to stop his affairs. It is needed a good timing to open up that moment for somewhat suggestions for his wife. If his day is almost happy and no worries you open up for him and let him promise not to get mad to tell somethings for him. Say it friendly and humbly to remember his wife so pity and lkove him so much.
